Our senses are still only tuned in to detect portions of "reality" that are relevant to life on earth. For example, our eyes detect the band of EM radiation most useful during daytime on Earth. But even though are eyes are narrow band and highly non-linear sensors, they (+our other equally flawed senses) have served us pretty well as far as understanding the true nature of EM waves.

I guess my point is that our senses still aren't evolving to detect reality in some sort of true pure mathematical sense.
